Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and more specifically, to a prefabricated steel structure node reinforcement connector. Background Technology

[0002] As a key form of modern building industrialization, prefabricated steel structure is based on the efficient on-site assembly of prefabricated components. Among them, beam-column joint reinforcement connectors are the core components that ensure the integrity of the structure. They are usually composed of columns, beams and matching fastening units. These structures directly determine the construction speed and structural safety. The current mainstream connection methods include welded joints, high-strength bolt connections and composite connectors, etc., in order to realize the force transmission between beams and columns.

[0003] However, in practical applications, the disassembly of traditional node connectors requires destructive cutting of the welded nodes, and the multiple high-strength bolts are very inconvenient to disassemble and install. Existing composite connectors require multi-step locking connection operations. These inconveniences in disassembly and assembly seriously affect the construction efficiency of prefabricated steel structures in scenarios that require frequent disassembly and modification, and significantly increase the cost of operation and maintenance.

[0004] In view of this, we propose a prefabricated steel structure node reinforcement connector. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this utility model is to provide a prefabricated steel structure node reinforcement connector to solve the problem mentioned in the background art that the traditional prefabricated steel structure node reinforcement connector has low disassembly and assembly efficiency, which affects the construction efficiency during disassembly and assembly.

[0007] 2. Technical Solution

[0008] A prefabricated steel structure node reinforcement connector includes a column and a beam connected in a T-shape. Mounting blocks are welded to both sides of the column. Each mounting block has a mounting groove with the same cross-section as the beam. Connecting blocks are detachably connected to the top and bottom of each mounting block. A plug rod and two limiting rods are fixedly connected to each connecting block. The two limiting rods limit the beam inserted into the mounting block. The plug rod locks the beam to the mounting block via a locking assembly.

[0009] Preferably, the limiting rod is cylindrical, and the top and bottom of the mounting block are provided with two first limiting grooves that are adapted to the size of the limiting rod, and the top and bottom of the crossbeam are provided with two second limiting grooves that are adapted to the size of the limiting rod.

[0010] Preferably, the cross-section of the insertion rod is rectangular, and the top and bottom of the mounting block are provided with first slots that are adapted to the size of the insertion rod, and the top and bottom of the crossbeam are provided with second slots that are adapted to the size of the insertion rod.

[0011] Preferably, the locking assembly includes a locking head elastically connected to the mounting block and a locking groove formed on the insert rod with a size adapted to the locking head. The locking head is used to limit the insert rod when inserted into the locking groove to prevent the insert rod from falling off.

[0012] Preferably, the locking head has a guide slope with an inclined surface at its side end, the mounting block has a movable groove for moving the locking head, both sides of the locking head are fixedly connected to sliders, the movable groove has a sliding groove adapted to the size of the slider, and the locking head is elastically connected to the inner wall of the movable groove by a spring.

[0013] Preferably, the connecting block is fixedly connected with a diagonal brace for reinforcing the connection between the column and the beam.

[0014] Preferably, both the connecting block and the diagonal brace are provided with unlocking slots for unlocking the locking components.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model achieves rapid positioning and locking of the crossbeam and column by setting detachable connecting blocks at the top and bottom of the mounting block, combined with the plug-in structure of the plug rod and the limiting rod. The matching of the mounting groove and the cross-section of the crossbeam ensures accurate initial alignment. The limiting rod directly constrains the radial displacement of the crossbeam, while the plug rod is axially fixed by the locking component. This reduces the time required for traditional welding and bolt tightening processes. Assembly can be completed with just a plug-in action. During disassembly, the connecting block can be pulled out by unlocking the locking component through the unlocking groove, which greatly improves construction efficiency.

[0018] 2. This utility model improves the operational error tolerance and ensures connection reliability by setting up a locking component and a guide slope. The locking head automatically engages with the locking groove of the insertion rod under the action of the spring, forming a mechanical interlock to prevent it from falling off. The inclined guide slope allows the locking head to retract when the insertion rod is inserted, until the locking groove is in place and the locking head springs in and locks. This mechanism reduces the complexity of traditional composite connectors that require step-by-step tightening, lowers the technical requirements for workers, and ensures the shear strength of the connection node through the setting of the limit rod and the insertion rod.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A prefabricated steel structure node reinforcement connector includes a column 1 and a beam 2 connected in a T-shape. Mounting blocks 3 are welded to both sides of the column 1. Mounting blocks 3 have mounting grooves 31 with the same cross-section as the beam 2. Connecting blocks 4 are detachably connected to the top and bottom of the mounting blocks 3. Insert rods 9 and two limiting rods 6 are fixedly connected to the connecting blocks 4. The two limiting rods 6 are used to limit the beam 2 inserted into the mounting blocks 3. The insert rods 9 lock the beam 2 to the mounting blocks 3 through a locking assembly. This modular design of the mounting blocks 3 and connecting blocks 4 enables rapid assembly and disassembly. The mounting blocks 3 welded to the column 1 provide rigid support, and the precise matching of their mounting grooves 31 with the cross-section of the beam 2 ensures effective initial positioning.

[0031] It should be noted that the detachable connecting blocks 4 at the top and bottom of the mounting block 3 achieve two effects through the insertion rod 9 and the limiting rod 6. The limiting rod 6 is used to resist shearing force, while the insertion rod 9, in conjunction with the locking assembly, withstands pulling force.

[0032] Secondly, the limiting rod 6 is cylindrical, and the top and bottom of the mounting block 3 are provided with two first limiting grooves 7 that are adapted to the size of the limiting rod 6. The top and bottom of the crossbeam 2 are provided with two second limiting grooves 8 that are adapted to the size of the limiting rod 6. With this configuration, the connecting block 4 can be quickly inserted by the cooperation of the cylindrical limiting rod 6 and the circular limiting groove. The first limiting groove 7 and the second limiting groove 8 can cooperate with the limiting rod 6 to suppress the radial displacement and torsion of the crossbeam 2. In specific implementation, the surface of the limiting rod 6 should be rolled and strengthened to ensure surface hardness.

[0033] Furthermore, the cross-section of the insertion rod 9 is rectangular. The top and bottom of the mounting block 3 are provided with first slots 10 that are adapted to the size of the insertion rod 9, and the top and bottom of the crossbeam 2 are provided with second slots 11 that are adapted to the size of the insertion rod 9. The setting of the insertion rod 9 further enhances the shear resistance of the connector and provides space for the subsequent connection of the locking component.

[0034] Furthermore, the locking assembly includes a locking head 15 elastically connected to the mounting block 3 and a locking groove 14 on the insertion rod 9 whose size is adapted to the locking head 15. The locking head 15 is used to limit the insertion rod 9 when it is inserted into the locking groove 14 to prevent the insertion rod 9 from falling off. With this configuration, the locking head 15 and the locking groove 14 elastically engage to form a self-locking mechanism, so that the insertion rod 9 automatically engages when it is inserted. In specific implementation, a fatigue-resistant bow spring can be used instead of a coil spring to improve the service life of the device.

[0035] The locking head 15 has a guide slope 17 with an inclined surface at one end. The mounting block 3 has a movable groove 12 for moving the locking head 15. Both sides of the locking head 15 are fixedly connected to sliders 16. The movable groove 12 has a sliding groove 13 that matches the size of the slider 16. The locking head 15 is elastically connected to the inner wall of the movable groove 12 by a spring 19. In specific implementation, the sliding groove 13 should be set in a way that does not penetrate the movable groove 12, and the locking head 15 should be located on the path of the insertion rod 9 into the first slot 10 and the second slot 11 in the initial state.

[0036] In addition, a diagonal brace 5 is fixedly connected to the connecting block 4 to reinforce the connection between the column 1 and the beam 2. The integrated connection between the diagonal brace 5 and the connecting block 4 can avoid the installation of additional fasteners and further improve the efficiency of installation and disassembly.

[0037] Specifically, both the connecting block 4 and the diagonal brace 5 are provided with unlocking slots 18 for unlocking the locking components. During disassembly, a rod-shaped object with a diameter smaller than the unlocking slot 18 is inserted into the unlocking slots 18 of the diagonal brace 5 and the connecting block 4 in sequence to press the locking head 15 into the movable slot 12, and then the connecting block 4 can be removed.

[0038] Working principle:

[0039] The mounting slot 31 of the mounting block 3 of the prefabricated steel structure node reinforcement connector of this utility model achieves initial axial positioning by precisely matching the cross section of the beam 2. When the end of the beam 2 is inserted into the mounting slot 31, the second limiting slots 8 at the top and bottom of the beam 2 automatically align with the first limiting slot 7 of the mounting block 3. At this time, the connecting block 4 is pressed down vertically, and its cylindrical limiting rod 6 is simultaneously inserted into the first limiting slot 7 and the second limiting slot 8, forming radial constraint, effectively suppressing the lateral displacement and torsion of the beam 2. At the same time, the connecting block 4... The rectangular insert 9 passes through the first slot 10 of the mounting block 3 and the second slot 11 of the crossbeam 2. During its movement, the end of the insert 9 contacts the guide slope 17 of the locking head 15. The inclined surface presses and drives the locking head 15 to retract inward along the movable groove 12. The slider 16 slides in the groove 13 to compress the spring 19. When the insert 9 is fully in place, the locking groove 14 aligns with the locking head 15. The spring 19 releases its elastic force and pushes the locking head 15 into the locking groove 14, forming a mechanical interlock. This ensures that the insert 9 bears the axial tensile force and bending moment, preventing it from falling off. During disassembly, the interlock can be released by pressing the locking head 15 with a rod-shaped object smaller than the unlocking groove 18, allowing the connecting block 4 to be pulled out quickly for removal and disassembly.
